Q: Ford Taurus 2004 right rear end damage resulted from backing up. Wanted to repair or replace the dented part. Estimate the cost.

I was backing up in the parking lot and accidentally hit my right rear end on a truck behind it. The truck was intact but my right rear end had a very deep and large dent (diameter of the dent is about 10 inches). The plastic cover of the rear end light was also damaged (the light can still work). I would like to get the light cover repaired. I also want a repair or replacement to be done so that my right rear end resumes normal looking. I would like to get a quote of the cost and potentially hire a mechanic to do the job.
